Xen for Centos 6.3 HowTo needs updating.

I was following the HowTo "Virtualization With Xen On CentOS 6.3 (x86_64) (Paravirtualization & Hardware Virtualization)" and was not able to complete the first page due to the following errors in the rpmbuild process.

I did notice that when installing libvirt-0.9.10-21.el6.src.rpm the howto mentions that we would get warnings we could ignore. I got a screenful of the warnings about mockbuild not existing - enough to fill my scrollback buffer. Would either of those make any difference?
